Support for ssh_config Include Statement

[mlist (chris)]

hi,

it would be great if CoreTunnel would support/respect the Include directive from ssh_config. As an alternative, it would help to include more than one ssh_config in the settings of CT.

Include

Include the specified configuration file(s). Multiple pathnames may be specified and each pathname may contain glob(3) wildcards and, for user configurations, shell-like “~” references to user home directories. Files without absolute paths are assumed to be in ~/.ssh if included in a user configuration file or /etc/ssh if included from the system configuration file. Include directive may appear inside a Match or Host block to perform conditional inclusion.

Source: ssh_config(5).

best regards,

chris

Hi Chris, Include directive is supported after Core Helper installed:

Core Helper

In order to work with local shell, authentication agent, system configurations and other advanced features, you must install Core Helper. How to install? Download Core Helper Installer application using the link below: Download Core Helper 4.2 Installer When the download is complete, launch Core Helper Installer by double-clicking it. After Core Helper has been installed, enable it in Preferences: [image] Why is this necessary? The apps on the Mac App Store must be sandboxed, it means t…

Hi Yang,
CoreHelper is installed - it doesn't work though. I'll try and gather some logs later today.
Anything obvious I could check? Settings->Advanced->Configuration is set to the default ~/.ssh/config ..

I was able to reproduce the issue on a new mac, latest MacOS, Core Helper installed:

A simple SSH config consisting of 3 files

~/.ssh/config
Include ~/.ssh/lan
Include ~/.ssh/wan

~/.ssh/lan
Host alpha
Hostname 192.168.0.100
HostKeyAlias alpha
Port 22
User chris
Identityfile ~/.ssh/keyfile

~/.ssh/wan
Host beta
Hostname 192.168.0.110
HostKeyAlias beta
Port 22
User chris
Identityfile ~/.ssh/keyfile

CoreTunnel immediately goes into retrying with "connection failed".

Both equivalent ssh commands work on the commandline. Here's the log for host alpha up to "connection established"

#> ssh -4 -vvv -o ServerAliveInterval=15 -o ExitOnForwardFailure=yes -o ServerAliveCountMax=3 chris@alpha

OpenSSH_7.9p1, LibreSSL 2.7.3
debug1: Reading configuration data /Users/chris/.ssh/config

debug1: Connecting to 192.168.0.100 [192.168.0.100] port 22.
debug1: Connection established.
...

Hosts defined in ~/.ssh/config are working fine.

best regards,

Hi Chris, could you please enable debug logging in Core Tunnel and paste the log again?

Enable logging

The default logging level is set to Info, Debug1, Debug2 and Debug3 each specify higher levels of verbose output. [image] Core Shell Open or go to Hosts tab, right click on the host and select Edit Settings… from context menu, navigate to Connection tab, then scroll down to Log Level option. Press ⌘ I (or select Shell -> Show Inspector from main menu) reveals shell session information, as well as log content. [image] Core Tunnel Navigate to tunnel's Settings…, Connection tab, then scroll …

This will help me identify the problem.

Thank you,

uhm, correct me if I'm wrong, but "debug3" will set -vvv for the command.
I've pasted the output of that up to "Connection established" in my previous post.

That's exactly my problem: CoreTunnel fails instantly while the equivalent command works. Is there a debug log for the Helper?

Did Core Tunnel printed any log? I understand that you've pasted log of the equivalent command, if any, could you please also paste the log of Core Tunnel?

Thanks,
